Error building
Closed this issue · 5 comments
I tried building from a fresh opam switch (4.07.1) and got the following error:
~/git/factorio $ make
ocamlbuild -no-links -use-ocamlfind -tag annot factoriojs.byte
+ ocamlfind ocamldep -package js_of_ocaml.syntax -syntax camlp4o -package js_of_ocaml -modules factoriojs.ml > factoriojs.ml.depends
ocamlfind: Package `js_of_ocaml.syntax' not found
Command exited with code 2.
Compilation unsuccessful after building 1 target (0 cached) in 00:00:00.
make: *** [_build/factoriojs.byte] Error 10
I tried installing js_of_ocaml-camlp4 but get the same error.
Sorry if this is an obvious ocaml question, I'm new to the language.
It looks like this might be an ocaml version problem. After downgrading to 4.01.0 I see the js_of_ocaml.syntax package with ocamlfind list. However I get some other errors. Which ocaml version is required for this project?
From readme, 4.03.0 is required but I think the js_of_ocaml-camlp4 package should be used instead of js_of_ocaml.syntax.
You are right, I discovered recently that the package name has changed... I think you can edit file _tags and replace js_of_ocaml.syntax with js_of_ocaml-camlp4 (note the dash instead of the dot) and it should work. Can you try it?
Once I better understand which version to use, I should update the README accordingly. Ideally, this should be configured automatically by detecting the version, but oh well…
Oh, actually you made a pull request with this exact fix :D
Side note: I think I had a weird situation with OCaml version 4.03 but with the older js_of_ocaml syntax package. When I reinstalled it on a new computer (for another project), I encountered the same problem as you and it took me a while to figure it out. Sorry you had to go through the same troubles.
